4.2.3. Key MODE/MXMNPK
A simple pressing of key MODE/MXMNPK allows for the following operations:
 Selection of measuring modes “AUTO”, “AC”, “DC”, “AC+DC” and “FREQ” in positions
V , LoZV
 Selection of measuring modes “AUTO”, “AC”, “DC” and “AC+DC”, “FREQ” and “IRC”
(see § 4.2.8) in position
 Selection of clamp transducer type in current measurement between options “ ”
(optional standard clamp) and “ ” (optional flexible clamp) in position
 Selection of measurements “AUTO” “TMR” and “PI” in position M (see § 5.6).
 Selection of measurements “AUTO” and “TMR” in position Lo (see § 5.7).
 Selection of measurement of Resistance “” or Continuity test “ ” in position 
A long pressing (>2s) of key MODE/MXMNPK allows for the activation/deactivation of
continuous detection of maximum value (MAX), minimum value (MIN), positive peak (Pk+),
negative peak (Pk-) of the quantity (voltage or current) to be measured. The values are
constantly updated and are displayed cyclically every time the same key is pressed. This
function is not active in position . Press and hold key MODE/MXMNPK (>2s) or use the
selector to exit the function.
4.2.4. Keys / e / ZERO
A simple pressing of keys / and / ZERO allows for the following operations::
 Setting of the full scale value of flexible clamp transducer (optional accessory - option
“ ” ) in position among values: 30A, 300A, 3000A for AC current measurement.
 Setting of the full scale value of standard clamp transducer (option “ ” ) in position
among values: 1A, 10A, 30A, 40A, 100A, 200A, 300A, 400A, 1000A, 2000A, 3000A
for AC and DC current measurement.
 Selection of harmonic order “DC ÷ 25°” in positions V , LoZV and
 Selection of calculation time of RMS value in DIRC function (see § 4.2.8).
 Setting of threshold values in positions M and Lo.
 Once insulation measurement is complete, the results appear on the display (M,
Vgen, PI, DAR).
Long pressing (>2s) of key / allows activating/deactivating display backlight. This
function is activated in any position of the rotary switch and is automatically deactivated
after approx. 2 minutes
’ idling. Long pressing (>2s) of key / ZERO allows for the
following operations:
 Zeroing of cable resistance in position Lo (see § 5.7)
 Zeroing of cable resistance in position  (see § 5.4)
4.2.5. Key VTEST/LIM
A simple pressing of key VTEST/LIM allows for the following operations:
 Selecting test voltage in insulation measurement among the following options: 50V,
100V, 250V, 500V, 1000VDC in position M
Long pressing (>2s) of key VTEST/LIM allows for the following operations:
 Setting the minimum threshold in insulation measurement among the following options:
no (no threshold), 0.10M, 0.230M, 0.50M, 1.00M, 100M in position M.
 Setting the maximum threshold for continuity test in range: 0.05 ÷ 9.99 in position
Lo.
